Chapter 7 - "The Boggart in the Wardrobe" - Malfoy takes advantage of his injury in Potions, Snape orders Ron and Harry to do his work, Black has been sighted near the school, Lupin conducts his first DADA class on confronting Boggarts.
Hagrid Teaches His Very First Care of Magical Creatures Lesson
The [Care of Magical Creatures] class leaves, with the [Slytherins] ranting about [Hagrid] letting [Malfoy] get hurt. [Harry], [Ron], and [Hermione] continue discussing the incident at dinner and back in the [common room], finally deciding to go visit Hagrid.
Down in [Hagrid's hut], [Harry], [Ron], and [Hermione] comfort [Hagrid], who is still upset over [Malfoy]'s injury in [Care of Magical Creatures]. Once Hagrid sobers up, though, he gets upset with the kids for walking across the grounds to see him late at night, and takes them back up to the castle.
In Potions Class
In [Potions] class, [Malfoy] returns from the [hospital wing] with his arm in a sling and manages to get [Snape] to order [Ron] and [Harry] to help him, while meanwhile [Neville] goes to pieces trying to get his [Shrinking Solution] to work, knowing that he'll have to feed it to [Trevor] at the end of the lesson to see if it works.
As [Potions] class continues, [Seamus] leans over to [Harry] and tells him that [Sirus Black] has been sighted nearby - and [Malfoy] proceeds to make fun of Harry for not knowing why he should want to go after him.
[Potions] class finally ends with [Snape] testing [Neville]'s [Shrinking Solution] on his toad, [Trevor] - and when it works, Snape takes points off from [Hermione] from helping him. [Ron] is outraged, but when he turns to talk to [Hermione], she disappears, leaving Ron and [Harry] suspicious.
Facing Their Worst Fears
At the start of [Defence Against the Dark Arts], [Professor Lupin] puzzles the class by asking them to put books away and follow him through the school. They pass [Peeves], who [Lupin] drives away by forcing a wad of gum up his nose, and enter the [staff room] - where [Snape] takes one last shot at [Neville] before departing.
Though the class is rather alarmed when [Professor Lupin] tells them they are to face a [boggart], [Harry] and [Hermione] answer questions successfully and Lupin prepares [Neville] to face the creature first by asking him to picture [Snape] in his [Gran]'s clothes.
[Professor Lupin] unleashes the [boggart] on his class, and they tackle it admirably, with the highlight of course being [Neville], who puts [Snape] in his grandmother's clothes. However, when the boggart gets to [Harry], [Lupin] intervenes and doesn't give Harry a shot, leaving him confused as the class leaves the room glowing about the lesson.
Chapter 8 - "Flight of the Fat Lady" - Defence Against the Dark Arts remains a favorite, Quidditch practice begins, Crookshanks goes after Scabbers, tension builds between Ron and Hermione, Harry is denied permission to visit Hogsmeade, Lupin talks to him about fear, Snape brews a potion for Lupin, Hallowe'en feast, and Black slashes the Fat Lady's portrait.
